have been used in all the views to indicate corresponding parts. In saiddrawing,

Fig. 1, is a sectional elevation showing my improved vat,

Fig. 2, is a top plan view of Fig. 1, and

Fi 3 to 5, are detail sectional elevations showing parts of vats ofmodified constructions.

In the example shown in Figs. 1 and 2 the vat comprises a bottom aressed into concave form and having a disc arge opening ba horizontalpartition c formed with apertures i, and side walls d supported on saidpartition. The said parts are internally coated with a medium resistantto acids and alkalis such as caoutchouc, and they are jointed with oneanother by means of screws and nuts,

a suitable packing medium being placed between the said parts, ifnecessary. The side walls d may be provided with openings or admittingor discharging the liquid. But I wish it to be understood that in somecases the liquid is poured into the vat On the partition c and aroundeach opening z' a ring 7c of soft caoutchouc or similar packing mediumis placed, and the .said ring 45. may be connected with the acid proofcoating of the partition. The bobbins m having the fiber material woundthereon are placed on the said ring for being washed within the vat, andfurther bobbins m may be placed on the lowermost set of bobbins-packingrings n and o made from soft c tchouc being placed between 53esuperfast.; In

Fi l I have shown two superposed bobbins, bu I wish it to be understoodthat any suitable number of bobbins may be placed one above the other sofar as is permitted by the height of the vat. The uppermost bobbins areclosed by means ofgdates p and packing rings n. The outlet b o the vatis connected by a pipe with a suitable pump adapted to Withof the vatand the pipe connected with the pump. f

In the modification shown in Fig. 3 the vatis provided with a flatbottom g, and the partition ris provided with a downwardly directedflange 1'l on and fixed tothe bottom g.

Further, the partition s may be made integral with the bottom t of thevat, as is shown in Fig. 4, in which case however, the discharge openingu must be sufficient in size to permit access to the chamber providedbetween the bottom t and the partition s for coating the said parts withan acid and alkali proof coating.

In Fig. 5 I have shown a modification in which the partition lv is madeintegral with the side walls Iw ofthe vat, and the bottom a: is formedwith an upwardly directed flange y on which the side walls 'w and theartition 'v are supported. In another mod' cation a concave ttom isused, asis shown in Fig. 5 in dotted lines.
